I've always had this doubt, isn't it an evolutionary disadvantage that the sperm is treated as a foreign object by the uterus of the woman, and that immune responses are initiated against the sperm? ...

What could be possible consequences of covalent bond mitochondrial and genomic DNA adduct by Fluoroquinolones, our study was done by Fluoroquinolone Toxicity Study NFP. All 50+ participates who took ...

Hopefully not a too-basic question for the venue. I'm a chile pepper growing hobbyist and have spent some time searching around and reading up on pepper (angiosperm) reproduction, but I'm not getting ...

I would like to be able to compare the risk for species to go extinct implied by their reproduction mechanism in the very short term. Imagine we choose some species A that can reproduce both sexually ...

For each stages of meiosis (i.e. Interphase, Prophase I, ...), I wanted to know the time between each stages either in percentages or minutes. However, while I could find the cell cycle for mitosis ...

I have attached a picture of this slime mold fruiting body which I took in my own yard. It is Mid-Summer (August), the air is humid but no rains. Earlier this month, a smaller one has appeared in one ...

18th century Feodor Vassilyev is said to have had children by two wives, each of whom only ever had twins, triplets or quadruplets. His first wife has 16 sets of twins, 7 of triplets and 4 of quads; ...

Suppose a flower having both male and female reproductive parts is self-fertilized then can this be called asexual reproduction...?I'm quite confused cause in this case the fusion of male and female ...

So I read about the sperm count decline in men in rich countries.
I wonder if this is accompanied by other changes for example in testosterone levels or in other hormones linked with the reproductive ...

In human reproduction the male produces sperm containing 23 chromosomes and the female has the oovum containing 23 chromosomes , so after fertilization the zygote contains 46 chromosomes. What I want ...

It is obvious that cell division in living organisms is now synchronised almost perfectly with DNA replication and, furthermore, the line of division has to intersect exactly the space between the two ...

Under which of the following conditions is Semelparous reproduction (where organisms produces all its offspring in a single reproductive event) is most likely to be favoured? (A) Adult survival rate ...

Due to the sheer number of sperm cells in an individual and the rate of mutations, are they likely to be incredibly diverse and encompass most of what we see across our species? For instance would it ...

I want to make a homemade beehive, I want to know how to differentiate honey cells and brood cells, therefore, I'd like to know how can I organize the beehive so bees will create honey and brood cells ...

Are there any water plants that grow fruit that is meant to be eaten? I’m specifically interested in plants that are not rooted permanently to the earth but are mobile for at least part of their life ...

I read somewhere that human chromosome 2 is the result of 2 primate chromosomes fusing together somewhere along our evolutionary journey. This is why we have 23 chromosomes while other primates have ...

This is something I just thought of while looking up stuff about matriarchies.
I recall a comic series I heard of once, I think it was called 'Y, the last man'. In that story, all males (besides the ...

I wonder how can semen use di/tri-saccharide (e.g. sucrose, trehalose, raffinose) for spermatozoa metabolism in preservation/cryopreservation of livestock semen, since the semen itself never bring any ...

In my (albeit basic) biology classes in the past, we've learned about how, to reproduce, two organisms must have the same number of chromosomes. This has been verified by a few other websites I found. ...

An offspring is 23 chromosomes of mother and 23 of father, if one of the mate learns say music after the birth of their first child— will their second offspring have better music skills than former? ...

My son studies genetics at school right now and they have been covering gender. It's well known that slightly more boys are born than girls. However, originally there's an equal number of sperm cells ...

It is traditionally taught that estrogen is produced by the granulosa cells of the follicle. But before menarche, where does the estrogen come from? Is it from the thin layer of granulosa cells lining ...

I'm currently trying to develop the world of a sci-fi story I'm working on, and a concept I've thought of adopting with the environment and characters is a common breeding system where identical twins ...

When reading a Wikipedia article to do with chickens, I have come across the term "clutch", but I was not able to entirely figure out what this word means. I was wondering whether the term clutch can ...

Suppose a new species is created from a random mutation that happened during an instance of reproduction in an existing species. How can that new species survive and flourish if there only exists one ...
